DEVELOPMENT AND VALIDATION OF A COMPUTER ASSISTED INSTRUCTIONAL PACKAGE IN BIOLOGY By Dr. Vandana Aggarwal

Abstract

Innovations in multimedia and computer-related technology offer exciting opportunities to impart quality education to students. One of the most powerful uses of technology in education has been to tailor instruction to students’ individual learning needs. Versatility of CAI to provide student paced instructional interaction in diverse array of contents with or without the assistance of a teacher makes it a unique instructional strategy that can be used to provide learning situations inside or outside the classroom. The process involves the interaction of individual students with computer which carries out multitasking: presenting the content, receiving, analyzing and acting upon students’ responses like a tutor. In the present study, CAI material was developed in selected topics of Biology for class IX students. The content was divided into modules based on selected biological concepts sequentially arranged from simple to complex. During the process of receiving instruction in each module and also at the end of each module, student is asked to answer multiple choice questions. Students can’t move to next module unless they master the concepts and answer all questions correctly. Validation of the developed CAI package was carried out by seeking experts’ opinions and by pilot testing on a sample of 50 students so as to ensure its suitability and effectiveness in enhancing students’ learning in selected concepts of biology. On the basis of the suggestions made by experts and responses of students, the CAI material was edited and finally packaged into a CDROM for its use in teaching and learning

Key Words: Computer Assisted Instruction, Biological concepts, Development, Validation.
